Underleveled Pokémon are Pokémon that are at a lower level than is usually available via evolution.

Overview

Underleveled Pokémon first appeared as early as Pokémon Red and Green, with level 4-6 Kakuna and Metapod available in Viridian Forest; Kakuna and Metapod cannot be obtained by evolution until level 7. Additionally, some non-player character Trainers use underleveled Pokémon in battle.

From Generations I to IV, Pokémon obtained in in-game trades are always the same level as the one being traded away, so many underleveled Pokémon can be obtained through in-game trades. For example, in Red and Blue and FireRed and LeafGreen, it is possible to obtain an Electrode as low as level 3, even though the species evolves from Voltorb only at level 30 or above. This Electrode can be obtained by catching a Pikachu in Viridian Forest at level 3, evolving it with the Thunderstone, and trading it on Cinnabar Island.

In the Generation V games Pokémon Black 2 and White 2, the introduction of Easy Mode lowers the strengths and levels of Trainer Pokémon by a few levels. As a result, the decrease in level would lead to many Trainers having underleveled Pokémon, due to some of their Pokémon who evolve by level up being at the minimum level of evolution in normal mode. Phenomena have a chance of triggering an encounter with the evolved form of a wild Pokémon native to the area, at around the same level as the other Pokémon in the area. This can cause underleveled Pokémon to be encountered, particularly in the earlier areas of the games, where the average levels of wild Pokémon are quite low.

In Generation VI, the introduction of the Friend Safari had also presented the opportunity to encounter many underleveled Pokémon, as all wild Pokémon that appear there will be level 30.

In Generation VII, the concept of SOS Battles makes it possible for an evolved form of a Pokémon to appear alongside the pre-evolution of the Pokémon. This new type of battling, along with all Pokémon that can appear within an area all sharing the same level range, means that SOS battling can bring forth many underleveled Pokémon. Totem Pokémon are also underleveled in the early to mid stages of the game due to the Totem commonly being an evolved Pokémon.

In Pokémon Brilliant Diamond and Shining Pearl, Pokémon found in the Hideaways of the Grand Underground have their levels based on the amount of Badges the player has acquired. As having only one places the range at levels 16-20, and two leaving the range at 25-29, it is possible to find underleveled Houndoom, Gastrodon, Skuntank (only in Brilliant Diamond) and Purugly (only in Shining Pearl).

Some NPC Trainers use underleveled Pokémon in battle. For example, Lance has three underleveled Dragonite in Generations II and IV, with one being at level 50 and two at level 49 in HeartGold and SoulSilver (Dragonite does not evolve naturally from Dragonair until level 55). Many other in-game Trainers, such as Mars and Jupiter, also possess underleveled Pokémon.

An application of the Pomeg glitch in Emerald makes it possible to evolve a Pokémon while it is still inside an Egg, allowing any such evolved forms to be obtained at level 5. In Generation IV, this particular exploit of the Pomeg glitch was fixed; the Pomeg glitch was removed entirely in Generation V.

Underleveled wild Pokémon

• The dagger symbol (†) next to the minimum level indicates that this Pokémon evolves through different means than reaching a specific level; therefore, its minimum level is inherited from its previous form.
• The asterisk symbol (*) next to the game abbreviation indicates that multiple games are required to obtain this Pokémon at that level.

Generation VIII

Generation IX

In Generation IX Incenses are no longer needed for Baby Pokémon to hatch, therefore most evolved forms of incense-produced baby transfered from previous generations can be underleveled.

Unobtainable underleveled Pokémon

Underleveled Pokémon from in-game trades

Prior to Generation V, since the Pokémon received in an in-game trade is the same level as the Pokémon traded for it, it is sometimes possible to receive a Pokémon at a lower level than normally possible.

In addition, some in-game trade Pokémon in later generations with fixed levels are also underleveled.

Underleveled Pokémon from Pokémon GO

Due to the way levels and evolution work in Pokémon GO, most Pokémon in the game can be obtained at levels as low as level 1, which can then be transferred to Pokémon HOME. In Pokémon GO, a Pokémon's starting power up level is affected by how it is obtained, with some methods allowing extremely low levels. Pokémon can be evolved without ever powering them up, so if a Pokémon can be obtained at a particular level in GO, so can all of its evolved forms (that it can evolve into in Pokémon GO).

Any Pokémon that can be encountered in the wild can be encountered at levels between 1 and 35 (with the maximum depending on the player's Trainer level and the weather). While Legendary Pokémon usually cannot be encountered in the wild (usually being exclusive to Raids, Research rewards, or Team GO Rocket Boss Giovanni), some have been made available in the wild—in particular:

When a Pokémon is traded, its level is capped at its new Trainer's level + 2. Since trading is unlocked at Trainer level 10, this means that all tradeable Pokémon in GO can be as low as level 12 after trading. Most Pokémon can be traded, except Mythical Pokémon (other than Meltan and Melmetal) and Shadow Pokémon (which cannot be transferred to HOME until after being purified, which changes their level).

Pokémon hatched from Eggs match the player's Trainer level at the time its Egg was obtained, capped at level 20. As a result, Pokémon exclusive to Eggs (such as baby Pokémon) can only be obtained at low levels (i.e. below 20) by players with low Trainer levels.

Pokémon obtained in Raid Battles are level 20 (or level 25 with weather boost), so Pokémon exclusive to Raid Battles (which includes several Legendary Pokémon and Mythical Pokémon) cannot be lower than level 20 without trading.

Pokémon obtained as Research rewards (including Research Breakthroughs) are always level 15, so Pokémon obtainable this way can be as low as level 15. This includes several Legendary Pokémon, Mythical Pokémon, and Ultra Beasts.

Upon purification, a Purified Pokémon's level increases to be equal to the player's Trainer level (unless it was already higher than that level), capped at level 25. Since the player can first encounter Team GO Rocket at level 8, Pokémon that can obtained as Shadow Pokémon can be as low as level 8 if purified by a Trainer with a low Trainer level.
